A laser produced extreme ultraviolet (EUV) source based on a water droplet target has been implemented an auxiliary electrode system between the source and the first collector mirror. The auxiliary electrode system creates a repeller electric field, possibly a dc voltage imposed on the mirror that slows down and reverses the trajectories of ions from the source before they impact the collection mirror. The source modified according to the invention was evaluated with respect to the demands of EUV lithography and found to have much extended operational lifetimes. The spectral distribution of the generated radiation as well as the conversion efficiency into line radiation at 13 nm was determined. Long time measurements of the reflectivity of silicon / molybdenum multilayer mirrors for up to from 107 to 109 shots show the useful influence of the treatment of ions emitted from the source. Several methods of debris reduction were tested and discussed. Surface analysis of the treated multilayer mirrors of is presented. Long time measurements of the reflectivity of silicon / molybdenum multilayer mirrors for up to 109 shots show the advantage provided by this invention.

A novel apparatus for and a method of estimating, calibrating and tracking in real-time the gain of a radio frequency (RF) digitally controlled oscillator (DCO) in an all-digital phase locked loop (ADPLL). Precise setting of the inverse DCO gain in the ADPLL modulating path allows direct wideband frequency modulation that is independent of the ADPLL loop bandwidth. The gain calibration technique is based on a steepest descent iterative algorithm wherein the phase ADPLL error is sampled and correlated with the modulating data to generate a gradient. The gradient is then scaled and added to the current value of the DCO gain multiplier.

PCT No. PCT / JP97 / 00572 Sec. 371 Date Jan. 8, 1998 Sec. 102(e) Date Jan. 8, 1998 PCT Filed Feb. 27, 1997 PCT Pub. No. WO97 / 31990 PCT Pub. Date Sep. 4, 1997This invention provides a method for reclaiming oil from waste plastic in such a way that thermosetting resins and solid foreign matter in the plastic will not pose a problem. This method greatly reduces the burden of presorting the garbage or industrial waste. To achieve this objective when oil is to be reclaimed from a waste plastic containing chlorine compounds, such as vinyl chloride, the plastic must first be stripped of chlorine. Prior to pyrolysis, while being conveyed forward in a continuous stream, the plastic is mixed with heated sand and / or an additive agent to raise its temperature to 250-350 DEG C. This creates a product which is comprised of a mixture of sand and substantially dechlorinated plastic. The product is mixed with heated sand to heat it directly to a temperature of 350-500 DEG C. It is maintained at this temperature until pyrolysis occurs. In order to obtain high-quality oil with a low boiling point, a first gas / liquid separation process separates the product obtained from the aforesaid pyrolysis into liquid high-boiling point oil, gaseous low-boiling point oil and low molecular-weight gases, and recirculates the liquid high-boiling point oil to the pyrolysis process, and a second gas / liquid separation process separates the gaseous low-boiling point oil and low molecular-weight gases into liquid low-boiling point oil and low molecular-weight gases. The first and second gas / liquid separation process are connected in sequence.

A resonant converter which can realize its easy design, eliminate the need for its adjustment, realize reliable soft switching operation, and increase an efficiency. A driver DRV of a main switching device uses a PLL circuit PLL to apply frequency tracking control in such a manner that a driving frequency fsw is made to track a resonant frequency fr (or 1 / N thereof, N being an odd number) and that the phase of the driving frequency fsw leads the current zero phase of the resonant frequency fr always by a desired time.
